IMPROVEMENT iN HARVESTERS.

Specification forming part of Letters Patent No. 78,800, dated J une 9, 1868.

To all whom, it 'muy concern: y

Bo it known that IfWILLIAM F. GOODWIN, of `East New York, in the county of; Kings and State of NewXork, have invented a certain new and useful vImprovement in Harvesters; and I declare the following to be afull description of the `same, reference `being had to the. accompanying drawiirgs,`wvhich form a part of. this specification, and in whiche v Iigure 1 Irepresents a top view of a harvester, showing my improvement attached. Fig. 2 is a side view of the same having one lof the carrying-wheels removed, showing my improvement attached to the multiplying-'gear on the shaft I*I,also showing the hoisting apfparatus by whiclrt-heijrame and cutter-bar are elevated and depressed., Fig. 3 isa detached seetionalniew of the angle or bell-crank,

showing the ball-and-socket joints." Fig. L is adetachcd .sectional viewof the hingejont by which the `cutter-bar is attached to the frame, showing the spring by which `the cutterbar is thrown down. I*1 ig. 5 is a detached seo- `tional view of the hinge-joint by which the cutter-bar is `turned to raise and lower the points ofthe fingers. e l 'v Letters A1, A2, B', B2, and \V represent the multiplying-gear on the shaft S.

s lLetter A represent-s the eccentric-cam; B, the canryokc, O, the connecting-rod 1), the angle-crank; E, the sl'ning by;\`\"h i eh lthe cutter-bar is thrown down; Ii, thepin by which ithe cutter-bar .is attached to the-hinged vi- `hratingblock (i. Gr is a hinged vibrating block, to which the cutter-bar is attached, and by which the cutter-bar is attached to the frame or shove. t

'lliisinvention consists `in the arrangement 0f mechanism by which motion is imparted orsi'ykle of'a harvester.

This invention is peculiarly adapted toa harvester having multi pl yin g-gcarmounted on its main shaft or axle. i

lhc cani. A is rigidly attached to and revolves wi l h thc pinion A2, the latter making the numbe r o f revolutions required to produce the number of vibrations `necessary for the knife or sickle.` The yoke B is fitted ou and isoperated by the cam A. The connecting-rod `Os `attached to the yoke `B by a vibrating joint, C', at its ripper end, and to 011e arm of the anglecrank` D by a ball-and-sockct joint, C?, Asaid angle-lever being connected by a similar joint to the rod e,1and the rod e is attached by its other end tothe cutting-knife or sickle. y

By this arrangement the motion is communicated from the multipl yin g-gean to the knife or sickle. `The cutter-,bar is hinged to the block Gr by means of the pin Ffor the "purpose of elevating anddepressing the points of the iingers. The block is hin ged to the frame for the purpose of elevating and depressing the cut,- ter-bar and to permit 'the cutterbar to vibrate and conform to the ground over which the machine travels. The springE serves to throw the cutter-bar down to the ground. The connecting-rod (J, being in line with the axis of the hinge-bolt, permitsthe cutter-bar to turn over `the tongue without interfering with the working of the knife or sickle.` The cutter# bar is raised and lowered by means of the chain f, pulley g, and ,lever h. By pulling the lever h toythe rear and pressing it down to the shaft II, the `cutter-bar is drawn up and turned over the tongue wit-hout stopping the operation of the knife or sickle. By letting the lever up and forward the cutter-barde seends to the ground or to its position for cuttin grain or grass. y A

"he advantage claimed for this improvements is, that by attaching the connecting-rod direct to the cam on the main shaft H, and by means of theangle-erank communicating the motion direct'tothe cutters or sickles, less'ma` chinery is required than when bevel-gears and crank-,shafts are used 5` and the arrange 1 e ,nient of the apljiaratus permits the eutter-bar `from the multiplying-gear to the cutting-knife 1 to swing up'into a perpemlieular.position or over the` tongue while passing obstructions ,without interfering with the Ioperation of the knife or sickle.

combination with the multiplying-gearshown may be drawn up andv turned over on the and described, for the purpose setforth.- tongue, in 'combination with the retraotin g1 2. The cam A, attached'to the pinion A2 or ,spring E, arrangedand ,l operated in the maua sleeve'projeeting from the latter, and workner and for the purpose substantially as deing on and rotating round the shaft H of a scribedk harvester, inthe manner and for'v the purpose WM.
